Special Effects Control

The Mission

Enable low-cost DMX control of practical fixtures and effects.

The Execution

I developed and built a custom control module with the assistance of associate designer Christian Curry. The main control module was built with three power supplies at the common voltages that the equipment we used required. Each power supply was fed through a monitor for voltage and current, to provide instant feedback for monitoring and troubleshooting on the output. Each supply fed a terminal block that could then be wired as needed into an 8 channel DMX relay that provided control from the lighting console, that also provided feedback of when a channel was activated. With the relays, it was possible to use both normally open and normally closed switch logic, which allowed us to do effects such as a magnet drop that needed to be powered the whole show.
